So your argument is that a highly complex system always existed (the laws of physics as you put it) but that isn't the only complex system you think always existed you believe every system including weather, life (birth), the complexities of the quantum realm, fire, and way more that I can't think of. Nothing in this universe is 'simple'. That is fine you believe a complex system always existed. I believe a extremely complex system always existed and it gave birth to our complex system. How exactly does your belief require any less faith than mine?
